SAW-HANDLE FASTENING.

SPECIFICATION forming part of Letters Patent No. 701,201, dated May 27,1902.

Application led August 9, 1901. Serial No. 71,510. (No model.)

T0 @ZZ whom, zt may concer-n:

Be it known that I, HARRISON E. HERRICK, a citizen of the United States,residing at and whose post-ofce address is Merrimack, in the county ofHillsboro and State of New Hampshire, have invented new and usefulImprovements in Saw-Handle Fastenings, of which the following is aspecification.

This invention relates to saw-handle fastenings; and the primary objectthereof is to provide a device of the character described which willeectually provide and compensate for the wear and tear on the sawincidental to the excessive handling to which an instrument of this kindis subjected.

It is well known thatconsiderable difficulty is experienced in keepingthe handle tightly secured to the saw, as excessive handling and thevibration cause the handle to work loose. In time a new one has to beprovided. By the use of my invention I obviate this diiiiculty, andthrough the medium of an eccentrically-mounted or cam lever a tightfastening is at all times made.

A further object is to provide a fastening whereby the handle may bereadily detached and applied without the use of any other tools than thehandle and cooperating parts.

The peculiar construction embodied in my invention will be clearlydescribed hereinafter and illustrated in the accompanying drawings, inwhich- Figure 1 is a vertical longitudinal sectional view through ahandle constructed in accordance with myinven'tion and showing the sawapplied. Fig. 2 is an end elevation of the handle and fastening In thedrawings, 1 designates a tube, in one end of which is sleeved the handle2. This tube is split longitudinally, as at 3, the lower portion beingreduced and terminating in an enlarged concave-convex end 4f, havingimpinging or abutting edges and 6, which engage and prevent slipping.

, 7 designates a transverse bar which is pivotally secured to the sleeveat a point intermediate its end and adjacent the top edge of the saw.The lower edge of the bar is designedto bear against the top edge of thesaw,

so as to firmly press the same against the abutting edges of the tube.It will be noticed that the top edge of this bar is cut away to form acani-face 8, and at the pivotal point of said bar is provided anelongated slot 9, in which the pivoted pin 10 is mounted. The object ofthis construction is to permita vertical play on the bar 7, so that whena downward pressure is exerted bythe cam-lever 11 the edge 7 n of saidbar will bear upon the top edge of the saw 1 evenly throughout itslength, thereby insuring a firm engagement by the impinging edges 5 and6. The handle 12 on the lever 11 is normally seated within the slot 13,and the T-head 14 thereof is curved, so that a finger may be readilyinserted in the recesses 15 to withdraw the lever from engagement withthe bar, and thereby release the saw. While I have specificallydescribed what to me at this time appears to be the very best means ofaccomplishing the desired result, I would have it understood that I donot limit myself to thevexact details of construction shown, but reservethe right to make such slight changes or alterations as suggestthemselves and `come within the scope of my invention. Y

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. A saw-handle fastening, comprising a slitted tube having aconcave-convex end to form impinging edges for engagement with the saw,a bar arranged Within the tube and adapted to bear against the top ofthe saw, and means forforcing' said bar in rigid contact with the saw.

2. A saw-handle fastening comprising a slitted tube having impingingedges at its lower end, a saw seated in said slit and engaged by theimpinging edges, means pivotally mounted in said tube for engaging thesaw and means for holding the engaging membei` in contact with the saw.

3. A saw-handle fastening comprising a tube having a vertical slittherein, a concavol convex portion in said tube, the edges of which areadapted to bear against the lower edge of the saw, and a leverl forholding said adapted to enga-ge the same to normally hold saw inengagement with said edges. it in rigid Contact with the saw. 1o
